“I don’t know yet,” said Grant. “Give me a chance.”
“Read it out loud,” urged John. “That’s the best way.”
“We, the undersigned,” read Grant, “hereby challenge the four boys who are camping on the island in the middle of the lake to a set of water sports. The events are to be decided upon by mutual agreement and are to be as many in number as may be agreed upon. We suggest that they include a sailing race, a canoe race, and a swimming race. The day for the sports is to be decided later and on Monday morning we will come over to see you and arrange the details.
Signed,
Thomas Adams.
Franklin Dunbar.
Hugh McNeale.
Herbert Halsey.”
“Who are they, do you suppose?” exclaimed John.
“I don’t know,” said Fred. “I never heard of any of them before.”
“They probably live in that camp down at the other end of the lake,” said Grant. “The one we visited the other day, you know.”
“And found nobody there,” added George.
“That’s it. They must be the ones.”
